Description

Technical Field

[0001] The utility model relates to the technical field of shoemaking, in particular to a mold for making the soles of rolled-edge cotton shoes. Background Art

[0002] The design of cotton shoes with curled edges is derived from the combination of traditional shoemaking techniques and modern aesthetic needs. Historically, in order to enhance the durability and structural stability of shoes, handmade shoemakers have invented a variety of reinforcement techniques, including curling the edges of the uppers. This technology not only improves the practicality of shoes, but also gradually evolves into a unique fashion element over time, and is widely used in various types of casual shoes, work shoes and even high-end shoes. Especially for cotton shoes that emphasize warmth and comfort, the curling design not only maintains the integrity and smooth lines of the upper, but also gives the shoes a more refined appearance.

[0003] However, in the manufacturing process of existing cotton shoes with rolled edges, since the rolled edge design is added to the upper, the upper and the sole are often manufactured separately, and then the upper and the sole are connected manually. That is, the rolled edge processing increases the proportion of manual operations, especially in the rolled edge sewing and finishing stages, which significantly reduces the production efficiency and affects the economy of large-scale production.

[0060] The pressing die comprises a left pressing die 3 for pressing on the left side die 9 and a right pressing die 7 for pressing on the left side die 9. A part of the rolled edge of the upper can be pressed between the left pressing die 3 and the left side die 9, and the rest can be pressed between the right pressing die 7 and the right side die 11. The inner edge of the left pressing die 3 has a first concave edge with the same shape and size as a part of the bottom surface of the sole, and the inner edge of the right pressing die 7 has a second concave edge with the same shape and size as the rest of the bottom surface of the sole.

[0061] It should be noted that the shoe last and the fixing bracket for fixing the shoe last are existing mature equipment in the field, and the specific structure and principle of the shoe last and the fixing bracket are not elaborated in this embodiment.

[0062] The working principle of the sole manufacturing mold 100 of the curled cotton shoes of this embodiment is as follows:

[0063] When the sole needs to be formed, the upper is first put on the shoe last, and then the shoe last is fixed on the fixed bracket, and the relative position of the fixed bracket and the bottom mold 1 should be adjusted in advance, so that the bottom surface of the shoe last fixed on the fixed bracket is directly opposite to the top surface of the bottom mold 1, and the distance between the two is equal to the thickness of the sole to be formed;

[0064] Then, the left mold 9 and the right mold 11 are brought into contact with each other, and then the left pressing mold 3 is pressed on the left mold 9, and the right pressing mold 7 is pressed on the right mold 11, so that a part of the curling edge of the upper can be pressed between the left pressing mold 3 and the left mold 9, and the rest can be pressed between the right pressing mold 7 and the right mold 11;

[0065] Finally, a set amount of molten material is injected into the molding cavity through the injection hole 20, the runner and the discharge hole 5. After the molten material solidifies, the mold can be opened to obtain the sole connected to the upper and the curling edge on the upper as a whole.

[0066] In the optional solution of this embodiment, it is more preferred to further include positioning convex strips, specifically:

[0067] The shape of the positioning convex strip is the same as the shape of the bottom surface of the sole, and the size of the positioning convex strip is larger than the size of the bottom surface of the sole; the positioning convex strip includes a left convex strip 15 fixed on the top surface of the left mold 9 and a right convex strip 18 fixed on the top surface of the right mold 11; when the left mold 9 and the right mold 11 are close to each other, the left convex strip 15 is connected with the right convex strip 18 to form a positioning convex strip; the bottom surface of the left die 3 is provided with a left groove 27 corresponding to the left convex strip 15, and the bottom surface of the right die 7 is provided with a right groove 29 corresponding to the right convex strip 18; when the left die 3 is pressed on the left die 9, the left convex strip 15 is engaged with the left groove 27; when the right die 7 is pressed on the right die 11, the right convex strip 18 is engaged with the right groove 29.

[0068] The engagement of the left convex strip 15 with the left groove 27 and the engagement of the right convex strip 18 with the right groove 29 in the positioning convex strips can, on the one hand, facilitate the positioning of the die on the side mold and improve the convenience and accuracy of positioning the die on the side mold; on the other hand, it can also prevent the molten material in the molding cavity from overflowing, thereby avoiding the formation of waste edges at the curling edge when injection molding the sole, which not only avoids the waste of material, but also avoids the subsequent process of removing the waste edges, thereby improving production efficiency.

[0069] In the optional scheme of this embodiment, it is more preferred that the spacing area between the left convex strip 15 and the first recessed portion is the lower left supporting area 16, and the spacing area between the left groove 27 and the first inner concave edge is the upper left pressing area 28; the spacing area between the right convex strip 18 and the first recessed portion is the lower right supporting area 17, and the spacing area between the right groove 29 and the first inner concave edge is the upper right pressing area 30; when the left die 3 is pressed onto the left die 9, a left accommodating cavity for accommodating a part of the curling is formed between the lower left supporting area 16 and the upper left pressing area 28; when the right die 7 is pressed onto the right die 11, a right accommodating cavity for accommodating the rest of the curling is formed between the lower right supporting area 17 and the upper right pressing area 30.

[0070] By pressing a portion of the curled edge of the upper between the left die 3 and the left die 9 and the remaining portion between the right die 7 and the right die 11, the position of the curled edge is fully fixed, and the molten material in the molding cavity can enter the lower left supporting area 16 and the lower right supporting area 17, so that the molded sole and the curled edge are tightly connected to form a whole, thereby improving the integrity of the manufactured curled edge cotton shoes.

By swinging the locking rod 19 toward the left mold 9, the slot 21 and the fixing rod 22 can be engaged; the engagement of the slot 21 on the locking rod 19 with the fixing rod 22 on the left mold 9 can ensure the stability of the position of the left mold 9 and the right mold 11, prevent the left mold 9 and the right mold 11 from separating from each other during the injection molding process, and improve the stability of the sole molding process.

[0074] In the optional solution of this embodiment, it is more preferred that the die further includes a left fixed frame 2 and a right fixed frame 6.
